Error code:-2147215357 Error code name:internal

Hi,

I've got a headache. A hit-in-the-face-with-a-sledgehammer headache. I'm creating a Java application which generates reports. The application is set up so that Crystal Reports may be created both through a http-request and through a bat-file that calls the main method.

When I run my application through my browser it compiles my beautiful report. But when I run it via the bat file (which includes exactly the same JARs that the web app does) I get the following error:

com.crystaldecisions.sdk.occa.report.lib.ReportSDKException: com.businessobjects.reports.sdk.JRCCommunicationAdapter---- Error code:-2147215357 Error code name:internal

Does anyone have any idea what can cause this error? I've would've jumped out the window a long time ago if it would be high enough to ensure a quick death. I should mention this application worked last week and as far as I can remember I haven't changed a single character in the source code. I've been struggling with this for six hours straight...
